I literally threw this together while cleaning out the frig. I was pleased with the results. The ingredients are approximate since I didn't stop to measure during my cleaning/cooking frenzy! After placing in oven I was worried the evoo may be too much with the cheese but it was not greasy. Servings and portions really depend on the size of the zucchini. My zucchini I guess was about 4 cups. I used 1/2 cup mex blend cheese that Zaar doesn't recognize as an ingredient.
